IMPROVEMENT V|N DEVICES FOR LOCKING-NUTS.

Specification forming part of Letters Patent No. 119,360, dated September 26, 1871.

To all whom it may concern:

Beit known that I, JOHN M. HORTON, of Milwaukee,in the county of Milwaukee, in the State of Wisconsin, have invented certain Improvements in Nut-Locks, of which the following is a specification My invention is a nut-lock or Washer which, when put onto a series of bolts and nuts, prevents the nuts from turning and keeps them in position. The center of this lockhas square holes punched in it to receive bolt-heads, and nuts to prevent thelnjrom turning. The end nuts are screwed down, and the ends of the lock are turned up and iattened down on the sides oi the nut and prevents it from turning.

Figure l is a view of a rail and joint with the lock attached; Fig. 2, a view of the lock open and ready to be put on.

A is the iron plate with the slots and'holes cut in it to form the lock. B and B are square holes punched in the iron A to receive the nuts and heads on the ends of the bolts. C and C are slots in the ends of the iron just large enough to receive the bolts. E and E are prongs that extend out beyond the nut and bolt, and D and Dl are prongs on the other side of the bolts and nuts.

The operation of this lock is as follows: The

bolts are put through the rail and the iish-joints on the sides, and the nuts are put onto the center bolts and secured up in place, then the lock is put on over these two nuts already screwed down, and the nuts put on at the ends and screwed down, and the ends D and E are turned back, as shown in Fig. l. This look can be used on anything else where there are two bolts only, if desired. f

I clailn- The locking-plate A having the angular perforations B B', the slots C C', and the lockinglips D D, all these parts" `being arranged as shown and described.

JOHN M. HORTON.
